Our role in planning and development

We are a statutory consultee in the planning system. As part of this role we advise on the potential impacts of development proposals and planning policies on Wales’ natural resources and environment

We are committed to supporting the delivery of sustainable development by working closely and proactively with our partners and customers to help direct development to the most appropriate locations

We are consulted by both planning authorities and developers for our expert advice on likely environmental effects from development proposals. We also advise local planning authorities preparing local development plans.

We seek to ensure that our advice is evidenced based, clear, and consistent to help determining bodies and developers make environmentally informed decisions.

We have developed Our Service Statement which sets out the standards of service that our customers can expect from us when we respond to consultations on planning applications and Local Development Plans. It also outlines the type of information we would expect from planning authorities and developers to enable us to provide effective and timely responses.

Our consultation topics sets out when we want to be consulted by planning authorities and applicants.

You can find out more about the service we provide to applicants by visiting the “Our service to developers" section.

Check the environmental constraints relevant to your development

You can use the spatial data available on ‘Lle’ to check some of the environmental constraints on our checklist that are relevant to your development.

‘Lle’ is a hub for data and information that was developed as a partnership between Welsh Government and Natural Resources Wales.

Please see below the list of environmental constraints on our development planning checklist you can find on the Lle Portal. Where they are not available on Lle we have provided a link to additional sources where you can find data and information.
